The Texas Instruments TPS3103K33DBVR is part of the TPS31xx family of ultralow supply-current voltage monitors. This supervisory circuit is primarily used for DSP and processor-based systems, providing essential circuit initialization and timing supervision.
Key features include a precision supply voltage supervision range, with options from 0.9 V to 3.3 V, and a high trip-point accuracy of 0.75%. The device operates with a typical supply current of just 1.2 μA. The RESET output is defined with input voltages as low as 0.4 V, and it includes a power-on reset generator with a delay time of 130 ms. The output can be configured as either push/pull or open-drain.
Designed for applications using low-power DSPs, microcontrollers, or microprocessors, the TPS3103K33DBVR is suitable for portable and battery-powered equipment, intelligent instruments, wireless communication systems, industrial equipment, and computers. It operates within a package temperature range of -40°C to 125°C and is available in a compact SOT-23-6 package, ideal for surface mount applications.
This supervisor monitors a single voltage supply and ensures proper system reset by maintaining the RESET output low as long as the supply voltage remains below the threshold. After the supply voltage surpasses the threshold, an internal timer delays the transition of the RESET signal.
